To aZZ whom it may concern:

Be it known that I, JOSEPH H. FISHER, a citizen of the United States, and aresident of Deerfield, in the county of Lake and State of Illinois, have invented new and useful Improvements in Frog-Rail Switches for Railway-Tracks, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invent-ion,

[O in which Figure I is a plan of a main track and side track of a railroad with which my improved'frog-rail switch is combined. Fig. II is a plan of the bed-plate at one end of the frog-rail, and Fig. III is a plan of the bedplate at the other end. Fig IV is a crosssection of the frog-rail and its base-plate. Fig. V is a vertical central longitudinal section of the frog-rail, its base-plate, the two bed-plates, an end of the abutting V-track, and the end of the rail to the main track. Figs. II, III, IV, V, and VI are enlarged about four sizes. Figs. VI and VII are details of the switch-crank devices.

This invention relates to improvements in frog-rail switches for railway-tracks which are held down by the abutting rails of the track, which project over and onto the ends of the base-plate attached to the frog-rail, whereby 0 the ends of the said base-plate swing between bed-plates and the under sides of the ends of said rails and in position to have salt brought to its upper and lower surfaces. The frograil is pivoted to swing from a main rail to 3 5 a switch-rail, and the construction is such that lifting up the ends of the rails abutting the frog-rail the latter can be readily lifted out of its place for repairs or otherwise. The frog-rail most resembling my invention is 0 shown in the patent to T. B. J ewett, January 13,1885, No. 310,591; but in this patent the base-plate to the fro -rail at its endsruns in grooves formed in plates which have metal interposed between the lower edges of the ends of the abutting track-rails and the top portions of the ends of the said base-plate, and therefore the frog-rail cannot be removed without removing the bed-plates which support the frog-rail.

Another advantage consists in a slight vi- 5o bratory movement the rails abutting the frog-rail may have by a train thereon independent of the bed-plates which support the base-plate, by reason of said rails having a separate attachment to the ties, whereby any ice is crushed at every passage of a train. 7

Further than this, the construction is simple and the cost is less than that of any other frog-rail which is properly held to its place.

A B are the rails of the main track, and 0 D are the long switch-rails to the same track.

E F are the rails of the side track, E being the inner or crossing rail.

G H is the V-track.

I J are the bed-plates which support the 'I .I has its top portion parallel with the under sides of the V-rail G H and the under sides of the track-rails E B, which bear, respectively, on said portions M and N and form the upper marginal support for the base-plate L by extending over its ends and holding it down. The base-plate L is of ordinary construction and projects outward at the sides of the frograil and ends thereof, the ends being held down by the rails of the track. plate may be apart of the frog-rail or secured to it, as most convenient, but in either case that portion of the rail and base-plate near to the V-rail should be pivoted to the bedplate J, as shown, that the base-plate may be swung from lugs or stops e c to a b to set the frog-rail to the side track.

In practice it is necessary that the frog-rail should be swung simultaneously with the rails O D. I therefore have employed an el- 0 bow-lever P, a connecting-rod 0, attached to the base-plate L, and a'rod Q, connected with the switch-connection R. The post of the switch is shown at V, the crank at W, the stand at S, and the lever at T; but these elements are not claimed to be new.

I claim as new, anddesire to secure by Letters Patent of the United States-- The base- 80 An improvement in pivoted frog rail on said portions N and M and pro j eating onto switches for railway-tracks, consisting of the the ends of the base-plate, as and for the pur- I0 bed-plates I and J, provided, respectively, pose specified. with the stops a e and b 0, and the portions 5 N M, having their respective heights equal JOSEPH FISHER to the thickness of the base-plate, in com- Witnesses: bination with a frog-rail provided With a pro- G.
